Strap for Black Bay 36 S&G - Diamond / Black - Diamond / Bracelet

The Tudor Black Bay One in 36mm version, reference 79653-0005, features a lug width of 19 millimetres. This specific measurement is the critical parameter for aftermarket strap compatibility. The measurement is taken between the inner space of the two metal lugs where the strap anchors. A strap with non-conforming lug width cannot be worn correctly.

For the two-tone stainless steel and yellow gold case of the 79653-0005, alligator leather represents the most elegant and visually coherent choice. Black or dark brown alligator amplifies the design's rigour, whilst cognac-coloured alligator creates a warmer chromatic dialogue. Alternatively, vegetable-tanned calf offers articulated texture that develops natural patina over time. For a sportier interpretation, a military-grade NATO fabric strap is practical and versatile.

Strap change is performed using a spring bar tool, a specialised instrument readily available online. Position the tool beneath the metal lug of the case, apply gentle pressure to push the spring pin inward, and the lug will release from the old strap. Repeat the operation on the opposite side. Subsequently, insert the same lugs into the holes of the new strap, ensuring they are properly secured and aligned. If unfamiliar with the procedure, the Casati Milano atelier offers professional strap-changing services with warranty.

Yes, absolutely. Online you will find a wide selection of straps compatible with 19mm lug width, the specific measurement of the 79653-0005.

The durability of a leather strap depends on material quality and frequency of use. Premium-grade alligator or vegetable-tanned calf, worn regularly (5-7 days per week), guarantees 3-5 years of use before the material begins to show significant wear. Shell cordovan is particularly resistant and may last beyond 7 years. To extend useful life, it is advisable to alternate different straps, allow the material to breathe, and protect against excessive sweat and moisture. The Casati Milano atelier provides straps with 18-month warranty.
